Abstract:

The semiconductor super lattices (SLS) have found wide applications in many electronic device structures and bio devices such as photo detectors, light emitters, avalanche photo diodes, compensatory transistors, tunneling devices, genetic diodes etc. The most extensively studied SL is the one consisting of alternate layers of GaAs and Ga1-xAlxAs, owing to its fabrication. The GaAs layers form the quantum wells and the Ga1-xAlxAs layers form the potential barriers. We wish to note that, the afore mentioned SLS have been proposed with the assumption that the interfaces between the layers are sharply defined with zero thicknesses so as to be devoid of any interface effects. As the potential form changes from a well (barrier) to a barrier (well), an intermediate potential region exists for the electrons. Thus the influence of the finite thickness of the interface on the carrier dispersion law becomes very important since, the carrier energy spectrum governs all the transport properties. In this paper, we shall investigate the DMR for the most interesting case which occurs in QDSLs of graded interfaces and compare the same with that of the constituent materials by formulating the respective one dimensional electron dispersion laws. The proposed approach has been implemented and tested on an embedded system, and it exhibits a good performance for monitoring / diagnosis applications.
